' DISAPPEARING WINDOW-SCREEN.

To all whom it may concern:

Be it known that I, ERNEST DE Wrrr, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Disappearing Window-Screens, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to disappearing detachable screens in connection with windows of an inclosure.

It is essential that the screens be conveniently located so that they will always be ready for use and securely hiddenwhen not in use.

The present invention seeks to provide an improved window screen preferably mounted on a roller hidden in the casing and attached to the window when in use, and

when not in use detached from the window and wound up on the roller thereby eliminating the necessity of taking down the the year andreplaclng them again in the spring of the year.

With these and other objects in view, the invention consists in the features of construction and arrangements of parts hereinafter set forth, illustrated in the accompanying drawing and more particularly pointed out in the appended claims.

In the drawings: Figure 1. is a view in elevation of a window and the improved screens, the screens being detached and a part of the view broken away to save room in illustrating. Fig. 2. is a view in vertical cross section of the window and improved screens, taken on line wa of Fig. 1, the lower sash being in closed position. Fig. 3 is a view in section taken on line bb of Fig. 2. with the lower sash raised. Fig. 4.

showing the spring ber 3, which is formed to fit'in the groove 4 of the sash 5, a slot being out near each end of the member 3 for receiving one end of the catch 6 which is secured on the shaft and mounted in the sash and turned by means of the handle 8 mounted thereon.

The roller 2 is mounted in the window casing 11, the screen passing through a slot 9 cut in the casing, roller by thespring 10, one end of rod 12 bein held securely to the casing by the brac et 13. The opposite end thereof is inserted in one end ofthe roller and one end of the spring is attached thereto at 14, the opposite end of the spring 10 being attached to the roller by means of the staple 15. Grooves 16 are cut in the window guides 17 and one end of the flat leaf springs 18 are mounted in the grooves, the opposite end being bent outward to force the screen against the guide 17 so that there will be no space between the guide and the screen, when the window is open the spring being forced back into the groove by the sash and out of the way when the sash is closed.
